RADIO TRANSFORMER.

Application led July 6,

This invention relates to a radio transformer. vAn object of the invention is to provide a simple and efficient transformer which is an improvement on the Well known 6 spherical type of coil.

Another object is to provide a simple and efficient construction which is economical to manufacture and assemble.

The invention is illustrated in the draw- Figure 1 is a perspective view; and

Figure 2 is a vertical section on the line 2-2 of Figure 1.

The form of the invention shown in the vdrawings is a preferred form, although it is understood that modifications in the construction and arrangement of the parts and in the character of the materials used may be adapted without departing from the spirit of the invention as set forth in the appended claims.

In its general aspect the invention comprises a substantially spherical coil having o en ends into which suitable insulating p ugs are disposed and to which plugs suitable bracket lates are connected to support the coil. Pre erabl wound around the great circle periphery o the-spherical coil, in a plane at right angles tothe axis of the basket 3o ball, is a primary, which is a woven ringlike coil separately Wound but disposed, as mentioned, and preferably vtied to the peripheryA of the coil in any desired mannen In the form of the invention shown in the drawings, I use a substantially' spherical coil 10 having open ends at 11 and 12 into which lit, preferably, insulating plu S13 and 14, to which plugs are connected racket plates 15 and 16 acting as supporting members.

Preferably, separately wound but in the assembly disposed on the spherical coil 10 is a ringlike woven primary 17 which is suitably tied to the basket-ball coil or secondary in any desired manner. This lprimar is preferably disposed aroundA a greatj circle 1925. serial No. 41,747.

periphery of the spherical coil, preferably in a plane vat right angles to the axis ofthe coil running through the center of the plugs 13 and 14. Suitable connections such as 18 and 19 are led out from the primary; and connections 20 and 21, from the secondary.

This transformer is found to be highly efficient, has a minimum loss, and is exceedingly simple and economical to manufacture. The construction as described requires a minimum amount of supporting material, thereby reducing losses.

1. A transformer, which comprises a spherical coil acting as a secondary, and a ringlike woven primary disposed around a great circle periphery of the secondary.

2. A transformer comprising a substantially spherical shaped coil .acting as a secondary, and a single ring-like woven primary coil associated with the secondary coil and disposed in a plane assing through the maximum diameter of t e secondary coil.

. 3. A transformer, which comprises a spherical secondary coil-having open ends, insulating plugs disposed in vsaid ends, bracket plates, connected to the plugs to support the coil, and av ringlike Woven primary disposed around a at circle periphery of the secondary at right `angles to the axis passing through the plug.

4. A transformer comprising a continuously wound secondary coil having` the form of a sphere, the several convolutions of the coil being self-sustaining, and a continuously woundY primary coil ofring-like con.- iguration encircling said secondary coil.

5. A transformer comprising a continuously wound secondary coil having the form of a sphere, the several convolutions of the coil being self-sustaining, and a. continu? ously Wound primary coil of ring-like configuration supported directly upon and encircling said secondaIr-y coil.
